Z1 Frameset

The Z1 is Felt’s most versatile road bike. With the longer wheelbase and taller head tube, the Z1 suits the racer as well as the gran fondo rider. Made with Felt’s Endurance Road UHC Ultimate + Nano MMC carbon fiber and using our proprietary InsideOut internal molding process, the Z1 is lightweight and surefooted in any situation. The Z1 fork shares the same features as the frame and is constructed from the UHC Ultimate + Nano with the carbon fiber ControlTaper 1.125" - 1.5" carbon fiber steerer tubes, integrated race, fork crown, blades, and dropouts.

This indicates the use of flow-through internal cable routing. It reduces wind drag and prevents contaminants from entering and interfering with the function of brake or shifter cables.

This bicycle is also available as a frame or frameset. Note that frame or frameset may not graphically mirror this complete bike.

InsideOut is a revolutionary internally optimized molding process that completely eliminates excess material, and therefore weight, inside the frame tubes and junctions. Placing polyurethane inserts inside the frame during the molding process—especially at the bottom bracket and head tube area—and then applying a precise amount of pressure and heat results in perfectly formed tubes, inside and out.

Modular Monocoque Construction is an advanced carbon fiber manufacturing technique that allows Felt to mold individual sections of the frameset and then join them together. The main advantage of MMC is that it allows each section to be optimized to meet the specific engineering demands of that particular section of the frame.

UHC Ulimate+ Nano is the mark of Felt’s lightest, stiffest, best performing frames. UHC stands for Ultra Hybrid Carbon, and as the name indicates these frames feature a hybrid blend of high modulus raw carbon fiber. The stiffest fibers are used in certain areas of the frame, more durable fibers in others. Nano refers to a proprietary resin matrix that increases frame strength at the molecular level.
